Скачать или смотреть Do Solar Panels Rust?

In the video, a worker is using a tool to remove a large amount of rust particles covering the photovoltaic solar panels.

A key fact is: solar panels themselves do not rust. Their main components are glass, silicon wafers, EVA film, and aluminum alloy frames, and these materials are highly resistant to corrosion.

The rust likely comes from industrial pollution in the surrounding environment: if the solar power station is located near an industrial area, a mine, or a railway, there may be a large amount of iron-containing dust in the air. This dust settles on the solar panels and oxidizes when it comes into contact with rain or dew, forming rust.

What are the consequences if they are not cleaned?
1、Sharp decrease in power generation → Rust coverage can cause a loss of over 50% in power generation efficiency, or even complete failure.
2、Permanent damage to the panels → Long-term buildup and friction can scratch the glass, reducing the lifespan of the panels.
3、Increased fire risk → Local dirt buildup can cause the "hot spot effect," where the blocked solar cells heat up. This not only reduces efficiency but can also burn out the panel, creating a safety hazard.

Final note: Regularly cleaning this type of serious pollutant is necessary maintenance to ensure the solar system operates efficiently and safely. It is not optional.
